Product design and engineering

Over 15 years of experience in product engineering and 3D modelling of parts and assembling. We combine our knowledge of production techniques and skills to design parts as a service to our customers. We design to manufacturing.

Industrial design

Industrial designers at Davantech are experienced in designing for maximum product features and specifications as well as for optimal manufacturing. At the beginning of every design project, our designers do extensive research into the basics—

Who your target users are

How your product will be used

Where it will function in

You want the design to communicate

Design and ergonomincs

The main aspects of marketability are design and ergonomics. Simply, design is about aesthetics—if your product does not look appealing, it will not sell. The value of a good industrial design is obvious: an attractive design not only helps to sell more products, but it also allows you to charge higher prices, which means that the actual profit per unit can be a multiple of the profit on a so-so looking product.

Ergonomics, on the other hand, focuses on the human interaction with a product: How does it feel in your hand? Do the shape and contours conform to the part of the body that comes into contact with the device?

Design for manufacturing

While design and ergonomics are instrumental to making a product marketable, they alone do not guarantee success. Careful consideration of production in the initial stage is crucial in product design as a sizeable percentage of the product’s lifecycle cost is committed at this time (cost of materials, production of parts, and assembly).

Davantech’s designers integrate design and industrialization into a single process, with the goal of designing a product that is easily and economically manufactured. This is achieved by early collaboration with mechanical and electronic engineers and production specialists to produce a design that fulfills price and manufacturing parameters, i.e., the relative ease to manufacture a product, part or assembly—while ensuring that design intent is preserved.

Some basic guidelines our designers follow:

Less is More

One of the best methods for reducing manufacturing costs is to reduce the number of parts in a product. Fewer parts often lead to less sourcing, development, purchasing, assembly, testing, development time and testing.

Make it Modular

The use of modules in product design significantly reduces the level of intensity of manufacturing-related activities. In addition, it provides ease in repairing, maintaining, or replacing a part of the device in the event the part were to fail.

Think about possible problems in advance

Tolerances can lead to failures. Its better to think about adjustments features in the early design. Once parts are being produced, devices are being assembled, it will cost a lot more to rework your product instead of adding some adjusting feature in the design.

Use Standard Components

Standard components are naturally less expensive than custom-made ones. The availability of these components means reduced lead times—the amount of time it takes to procure components. Using standard parts also offers peace of mind with regard to the components’ reliability. We have a huge chain of suppliers for standard components.

Keep it Simple

Design with ease of fabrication in mind. To minimize manufacturing cost, we select the optimal combination between material and fabrication process. By and large, secondary operations such as painting, coating, and surface finishing should be avoided. Requiring a high degree of precision on parts should also be avoided whenever possible as this poses manufacturing challenges and increases the reject rate (yield loss), resulting in higher part production cost.

Plastics like to be rounded

Use rounded corners as opposed to sharp angles since plastic flows better through rounded corners during plastic injection. Concurrently, (draft) angles—an angle incorporated into a wall of a mold so that the opening of the cavity is wider than its base—are needed so that a plastic part can be released from the mold without damage.

In addition, design minimizing assembly directions. Electronic products should be assembled from one direction— ideally from above. This way gravity works with you during the assembly process as opposed to slowing down assembly by having to compensate for its effect.

Mechanical engineering

At the beginning of a new product engineering project, our designers will study the required specifications, form factor and functions of a product. This ensure that the most suitable design, material, and manufacturing process is selected and thus warrants the most optimized cost structure and performance of the product. A good mechanical design is crucial in the development of any electronic or mechanical product.

Mechanical engineering involves :

Selection of materials

Manufacturing processes

Strength of enclosure and parts

Injection mold design

Assembling time

Production cost

Thermal management

Reliability electronic components MTBF

Dust and water resistance IP Rating

EMI/EMC : Electromagnetism

Maintenance, repairing

Environmental specs : shock , vibration, ..

We offer our clients the highest quality product engineering solutions that work within technical and price constraints and fulfill project objectives. Our mechanical engineers are unique in that they adept at reconciling technical solutions with price and manufacturing constraints. This allows us to develop reliable mechanical systems and enclosures that are practical, cost optimized, and able to be manufactured at whatever production quantity.

Prototypes

A prototype is to verify the electronic or mechanical development process and is an essential part in the design, development, as well as certification procedure. How an electronic product will respond to user input and handling is difficult to evaluate without experiencing them first hand. As a tool in the development process used to validate electronic and mechanical design, a prototype is crucial.

During the development stage, several working prototypes may be produced and are tested by our engineers. The prototypes are then sent to our client for further testing in the field to gather feedback and to identify bugs and possible improvements that will later be corrected.

Once a prototype has undergone sufficient testing and validation, a pre-production prototype is then regarded as the “golden sample,” which is used as the benchmark or standard on which mass produced units will be based. This golden sample is also used for certification purposes and sent to a third-party testing facility for CE, UL, FCC, or ROHS markings.

As opposed to a working prototype or a pre-production prototype, which are produced toward the end of development, more rudimentary prototypes may be made during the early stages of development in the form of a Proof of Concept to prove the idea works from a technical standpoint, or as a Mock Up to simply convey shape and size but not the function, material, or production methods of a final mass produced product.

Note: We only produce prototypes in the scope of a product development and manufacturing project. We don’t offer prototyping as a sole service.
